BILGE 'sUeTIoN STRAIHER on sinrs.

Application fllc'wscpfemb'cr'm; 1928. Serial N01 662,181

One of the objects of the present inventionis'to provide an improved suction strainer for the bilge of ships.

A "further object of theinvention is to providea removable strainer by means of; which shavings, cotton waste and other rub-- accumulated with water in the hish usually bilgeiof ships can be readily" removed.

A further object of the invention is to rangenient' of the various parts in the "ma n'- nor hereinafter described and" particularly pointed out in the appendedclaims.

Referring tovth'e drawings, Fig l is a top plan View of my'improved. bilge-strainer for ships, and i I Fig. 2 is a cross sectional View taken 'on the lines 2-2 in Fig. 1.

\ Considerable difficulty is nowexperienced in the removal of the accumulated i water', oil, cotto'n waste; and rubbish 'in the "bilge of's'hips w'hen the' st-rainer connected to the suction pipe and'subm'erged'beneath the ac= cumulated water 'and other refuse becomes clogged, in that it requires an attendant to work beneath the wateuto clean and clean the slil f-ilnel'l' In' ordor to overcome this (lllll-F culty' I haveprovided a construction ofa suction strainer by means of which the accuinuiated" cotton waste; shavings "and other rubbish may be reedilycollectedin a strainer int-he form of abucket and removed'from the casingadjacentthev end of the suction pipe and cleanedoutand returned to its normal operative position." FOlTt-lle purpose of illustietion'I have shown my improved bilgeistrainer col'uprising a casingfi which consists of an" enlu'rged'oylindrical oompart l ment 6 having an enlarged circular aperture 7 on theitop side thereof and it relatively men-e1 circular" aperture 8 on r the bottom side thereofr The "relatively smaller circular aperture 8 is positioned in axinl 'aligninent wi'thlthe aperture 7 in the top SldeOf said casing. Positioned adjacent tl e' '=circular aperture-8 and formed as an; integral part of'thelbottoin" 9 'of the casing- 5 are four upwardly extending guiding: members 10; These guidingtmemhers are positioned rfid+ jacent the periphery of the aperlu'lre '8 and spaced apart litsubstant-ially ninety degrees about the periphery. The g ruiding members 10" are provid'edwithinclined or bevelled surfaces 11 'which are normally employed. 1

.for' guiding the bucket or 'strainer'into ltS seat .in thecusing' '5 in the munner'hereim after described. Extendiiig laterally from and formedintegrally with the" enlarged compart'ment"6v of the casingw5 is a. neck portion-12. Also formed integrally with this neck, portion 12 and extending laterally" therefrom'is a semi-circular compartment or casing 13; The casing'or compartment 13 provided with a circular bottom 14' having an indentation or concavity 15 formed centrallytherein. Extending around the bottom 14 adj acent one-half the periphery thereof'is a se1ni+oiroulargr0ove 161' The cemircitrcular' groove 16 isudap'tedto' relnovably receive a semi-circular casing or cap '17. l Thecap or casing l'i is adapted tombe removably secured tothe semi-circular" compartment or casing 13 by a. tapered ring 18 Whichirictionally secures two semi-circular collars 19 and 20, which are'forrned integrally with the semi circular' casings'l'i'" and 18, respectively; In order'to further retain these cooperati'ng 0r interengaging parts from becoming :dis; engaged from each 0tl1G1,I haveprovided an interlocking proj eotion 21' formed integrally with the semi=circular collar 19 adaptedto interenga'ge with "aco-operating recess "portion 22 forlned in the semi-circular collar 20 of the" casing 13; it being understood, of

course; that two, such 'like-rco-operetiug"on therein flSTZl. suction 'pipe 23 which extends vertically into the semi-circular casings 13 end17'to a pointadjacent the depression or concavity 15 formed. in the bottom 14;; as shown ill/"24: The suctionpipe- 23 ofcourse forms the connect-ion running tothe pump of the ship? i From the abm'e description, 'it will readily be seen that by removing the tapered ring for drawing. the excess water 1 from the bilge 18, which frictionmllyeecures the semicir cu'lar collars 19' and 20 ofithe' semi-circular casings .17 and 13, respectively; the cap or! semi-circular casing" 17 i may be readily Iree moved "from the semi-circular. groove 16 and theco-operatinginterengaging portions an inverted frustum of a cone.

integrally with or secured to, many well of the semi-circular; collars 19= and 20 also disengaged, and thereby permit-the casing 5 to be entirely detached from the suction pipe 23 of the pump, My improved..removable stralning bucketfcomprises a skeleton frame work as shown at 25, which consists of four diverging members 26 extending substantially at right, angles--to each" other and forming the concave bottom of the, bucket; 'Each of these-four "members extend upwardly and outwardly at a slight angle with respect to the vertical; as shown at 27, so as to givevthe bucket the form of Formed known manner, adjacentthe tops of. the inclined members 27 is an eneirclin'gor retaineing ring 28 which forms the upperior top pbrtionof the bucket. hiountedwithimthe skeleton bucket and secured therein fuinf any well'known manner is a wire mesh 29. which 'forms the strainer for the bottom and sides and-through which all the water must pass before'entering. the innerchambers of p In order to lock the bucket'within the casing or compartment the compartment 6 or 13.

6 Ihave provided oppositely disposed latching members 30 pivoted at 3'1 to oppositely positioned ears 32 formed integrally with the-retaining ring 28; The latching members '30 areadapted toactuate within the.

slots 33 formed in the retaining ring 28 -between the ears 32. The latching members 30 have formed integrallytherewith adjacent their pivot 31 pawl portions 34 which .are adapted to engage the underside of the top of the casing or compartment 6- adjacentthe periphery of the enlarged" aper-- ture 7. Secured to the inner ends of the latching members 30 are two cableor chain 3 connections 35 which extend upwardly and are connected together by arsinglering or Ylinkmember 36. The ring or linkmember 36 is connected bya rope ora cable, not shown,' to a hoist which may be used; in hoisting thebucket strainervwhen'the same isremoved from itscasingh.

From the above description it will be seen that as the'strainer bucket25 is lifted from its seat in the casing, prior to such litting, the latching members 30 are actuated about their pivots 311 in the ears 32Yuntil 5 they assume a position in which the pawl portions 34 of these latching members -become disengaged from the underside of the s top of the casing and as the chains 35 are further lifted the bucket'25 is entirely removed from itsiseat in the casing. Vvhen it is desired to return the bucket to its seat in thecasing-thebucket is lowered' toa position in which the" bottom of the same enters the circular aperture 28' in the top v of thecasing 6 and the sides 27 ofthe bucket proper engage the inclined or bevelled edges 11 of" the upwardly extending guide -memwith great facility.

Vhat Iclaim as my invention and bers 1O securedtothe bottom 9 of'the casing adjacent the periphery of the circular'aperture 8,,and then as the chains 35 are further lowered the pawls 3e of the latching members' 30 are actuated to the locking posi-' tion, or the position shown in Fig. 2 by the weight of these members. a my lmproved bilge -Sl3lfl1I1Q'I', 1t Wlll be I In the use of readily understood that the same is completely submerged beneathpthe wat'er and that the pump draws the water from thebilge of the ship through "the medium of. the suction pipe-23p all the water'must pass through the wire meshing ofthe bucket forming the bottom and sides thereot' and enter the enlarged chamber, or compartment 06, passing from this chamber throughthe fviously described. Y I-f'difliculty is found in seating the bucket in the casingywhichfis normally submerged below the surface of the water, a guiding member may be secured centrally in the bucket'or' at the sides of the bucket having its lower end secured in any well known manner to the casing and extending above the surface'ot the water to which the bucket may be slidingly con-' i nected in order that thesame may-be"prop-- erly' guided toitsseat. in'theeasing.
